Abstract: In a method for acquiring dynamically varying magnetic resonance signals, a respiration cycle of a patient is monitored in a learning phase. Acquisition of varying signals ensues with the highest possible temporal resolution in an initial phase with a breath-hold by the patient. Slowly varying signals are subsequently acquired with lower temporal resolution in a movement phase and with free respiration of the patient. The signal acquisitions are initiated by a pre-established trigger condition.

Abstract: In a method, tomography apparatus and software product for evaluating time varying diagnostic images, a series of images are obtained in a time sequence from an examination subject in a tomography system, the sequence including exposures in a first image dataset obtained before occurrence of a diagnostically relevant event associated with the subject, and a second image dataset obtained at or after the event. A first correction of the image data is undertaken by displacing the image contents in each image to bring the position of the subject in each image into coincidence. A second correction of the image data is undertaken by obtaining an average value image from the image data corrected by the first correction. All of the images in the first and second datasets, corrected by the first correction, are normalized to the average value image on a picture element-by-picture element basis.

Abstract: In a method for magnetic resonance imaging, with which an imaging magnetic resonance measurement of a region of interest in an object under examination is carried out, and a tomogram of the region is displayed, that can be prescribed in position and orientation, and a two- or three-dimensional magnetic resonance overview image of at least a part of the object under examination is made before the imaging magnetic resonance measurement. In the method an envelope of the part of the object under examination is determined automatically from the magnetic resonance overview picture, and the dimensions of a minimal measuring field for the imaging magnetic resonance measurement are automatically calculated from the position and orientation of the prescribable slice, taking account of the envelope, for which no folds, or a prescribable measure thereof, occur in the tomogram. Optimal adaptation of the minimal measuring field to the respectively selected slice in a simple manner.

Abstract: In a method for controlling a tomogram acquisition device acquiring tomograms of a subject and a control device and tomography apparatus operating according to the method, reference images of the subject are presented at a graphic user interface, and the positions of tomograms to be subsequently acquired are defined by slice position markings within the displayed reference images. A sequence of time-dependent slice position markings is first set in the reference images, with a time mark being allocated to the individual slice position marking of the sequence. On the basis of this sequence of time-dependent slice position markings, the positions of the tomograms to be subsequently acquired are determined dependent on the acquisition time of each tomogram relative to a reference time.
